slope-intercept, standard, point-slope form

Slope-Intercept form is

• y=mx+b

• Ax+By=C

• y-y1=m(x-x1)

Standard Form is

• y=mx+b

• Ax+By=C

• y-y1=m(x-x1)

Parallel lines have the (a)   slope. Perpendicular lines have​ (b)   slope.

• same
• negative reciprocal

Point-Slope form is

• y=mx+b

• Ax+By=C

• y-y1=m(x-x1)
